Borussia Dortmund have stated they are not willing to Sancho after he joined in preseason training on Monday.
However, reports claim United still think they can complete a deal for the England international.
But speaking after United beat FC Copenhagen to reach the Europa League semi-finals when asked about Sancho, Solskjaer replied: "I can't comment on other team's players, I can't do that. You know that. I never do."
The saga will continue to roll on this summer as United try to sign their number one target.
The Red Devils will face Sevilla in the semi-finals in Dusseldorf on Monday.
